Description
Technical field
The present invention relates to the preparation of the defoamer that uses in a kind of sugar industry, it is the compound synergic by high viscosity silicone grease, low viscosity silicone grease and higher aliphatic polyethers, but has reached the purpose that froth breaking soaks soon.Its invention relates to the preparation of fine chemicals additive, and therefore, the present invention is under the jurisdiction of technical field of fine chemical preparations.
Technical background
In the sugar industry production process, liquid glucose stir, flow with factor affecting such as conveying under mix with air and to contact, easily produce a large amount of foams.The generation of foam usually makes the liquid glucose case emit pot, causes loss of material, and how foam also influences the conveying of liquid glucose simultaneously, causes operating difficulties.In evaporation and crystallization workshop section, the foam of stiff has slowed down the evaporation and the crystallization rate of moisture, increases energy consumption, influences sugar refinery economic benefit.Therefore the generation of elimination and inhibition liquid glucose foam is the problem that pay much attention in sugar refinery.The method of eliminating foam generally has two kinds of mechanical physical defoaming and defoamer froth breaking methods.Since defoamer froth breaking method have save time, the advantage of laborsaving, small investment and instant effect, so all be that defoamer comes froth breaking basically in the Closed Circulation in Sugar Production at present.
The sugaring defoamer is the same with other industrial defoamers, and generally all should possess following condition: surface tension is lower; Be insoluble to or be slightly soluble in by the medium of froth breaking; With the compatibility that is had by the froth breaking medium to a certain degree; Can be dispersed in very soon in the froth breaking medium, have good chemical inertness; Be unlikely to production process and production equipment are impacted.
Traditional sugaring defoamer has vegetable oil, turkey red oil and chilli oil powder etc., and according to surveying and determination, wherein the part defoamer has the possibility that works the mischief to human body, has been limited in the sugar industry and has used.Present stage uses in sugar industry and mainly contains following several defoamer more widely: (1) polyether antifoam agent; (2) silicone defoaming agent, the silicone defoaming agent surface tension is low, and good chemical inertness is arranged, and solubility is little in the medium, and froth breaking is fast, is a very potential defoamer; (3) polyglyceryl fatty acid ester; (4) sucrose fatty ester defoamer; (5) product of multiple defoamer or additive compound, this series products use the different antifoam compositions increase effect of learning from other's strong points to offset one's weaknesses, and make the advantage of product have more comprehensive.
The defoamer of in patent ZL96194968.6, mentioning, be mainly the polyethers component, antifoam composition is single, can not obtain froth breaking, press down all good effects of bubble, though ZL92112223.3 mentions with polyethers and silicone based for the froth breaking component, the silicone based froth breaking component that adopts is single low viscous silicone grease, generation to press down the bubble effect relatively poor.Based on this, the inventor has developed novel sugaring defoamer through great deal of experimental, and it is handled through processing by high viscosity silicone grease, low viscosity silicone grease and higher aliphatic polyethers and forms, and its antifoaming performance is all good, and consumption is few, is eco-friendly product.
